711 Marmulla

711 Marmulla is an asteroid belonging to the Flora family in the Main Belt. It was discovered 1 March 1911 by Austrian astronomer Johann Palisa. The asteroid name may be derived from the Old High German word 'marmul', which means 'marble'. This asteroid is orbiting $2.24 AU$ from the Sun with a period of 1222.4 days and an eccentricity (ovalness) of 0.195. The orbital plane of 711 Marmulla is inclined at an angle of 6.1° to the plane of the ecliptic.

Photometric observations of this asteroid in 2019 resulted in a light curve showing a rotation period of $2.721 hours$ with a brightness variation of 0.06 in magnitude. This result is consistent with a similar study earlier in the year. A. Kryszczynska and associates had found a slightly longer rotation period of 2.88 hours in 2012. The low amplitude of the variation suggests a nearly spherical shape. The spectrum of 711 Marmulla most closely matches an A-type asteroid.
